Introduction

Gebiideans are small lobsters with symmetrical chelate or subchelate first pereopods and subchelate or simple second pereopods. Gebiidea is one of two infraorders until recently considered part of Thalassinidea Latreille, 1831 (Poore et al. 2014; Robles et al. 2009). The other is Axiidea. The two infraorders are probable sister taxa or not, according to the molecular data used (Timm and Bracken-Grissom 2015). Gebiideans are separated from axiideans in the possession of enlarged chelate or subchelate pereopods 1 and subchelate or simple pereopods 2 (Dworschak et al. 2012; de Saint Laurent 1979). Most species are cryptic burrowers in mud, sponges or corals.

Diagnosis

Sponge shrimps, mud lobsters. Carapace more or less cylindrical, longer than wide; epistome short, not fused to basal antennular and antennal articles, with narrow point of contact with lateral margin of carapace. Exoskeleton calcified, or chitinised (rarely). Thoracic sternite 8 free from thoracic sternites 1–7. Pleon elongate, muscular; pleonite 2 pleuron overlapping pleonites 1 and 3, or all pleura overlapping next most posterior pleuron. Antennular penduncle articles aligned linearly, main flagellum long, lash-like, aesthetascs more-or-less evenly distributed. Pereopod 1 large, chelate or subchelate; pereopod 2 subchelate or simple. Pereopod 5 shorter than others, subchelate. Uropods biramous.
